YouTube Sentiment Analyzer is a free Chrome extension designed to evaluate the sentiment of comments on YouTube videos. By analyzing the tone and style of user comments, it provides insights into the community's feelings towards specific content. This tool serves as an alternative to the removed dislike feature, offering a deeper understanding of audience reactions.

Key features include the ability to scroll through comments for sentiment analysis without restrictions, the option to utilize the official YouTube API for faster processing, and customizable limits on the number of comments analyzed. Additionally, the extension weighs the sentiment based on likes received on comments, ensuring a more comprehensive evaluation. Sentiment can also be automatically calculated upon video load when using the API, streamlining the user experience. Currently, it supports comments in English, with plans for future language expansions.
